The first batch of new ambulances, based on the Mercedes-Benz Sprinter 519 CDI chassis and fitted with purpose-designed box bodies by German specialist WAS, has just been delivered, with a total of 147 vehicles due to enter service by the end of 2014.

Most of them will replace older vehicles which are being phased out but there will be a net increase of 27 in the size of the fleet, taking the total to 310.

John Hole, head of fleet at the East of England Ambulance Service NHS Trust, said: “The 5.0-tonne Mercedes-Benz Sprinter is well proven in operation and offers the combination of performance, reliability, safety and carrying capacity that allows us to provide a high-quality service to patients.

“Orwell Truck & Van is our preferred dealer and a company with which we have enjoyed a very good relationship over many years.

“It provides an excellent service, maintaining some of our ambulances in its workshops, and supplying parts to our own facilities in Norwich and at Barton Mills, Suffolk.”

Jonathan Ager, dealer principal at Orwell Truck & Van, which has centres in Ipswich, Colchester, Newmarket and Norwich, said: “We’re delighted to have won this order from the East of England Ambulance Service.

“We now look forward to maintaining our excellent relationship with the trust and to playing our part in delivering this important local service,” he added.
